What software do you use to link computers?

I want to link my indoor office computer with my observatory computer which is about 50 metres away.

What software works best for that? I remember being told before teamview is good.

What would you recommend?

I have a long Cat 5 cable I am trying to put plugs on at each end and use. I got the plugs on but not sure if they have been wired up properly.

Is there a simple test? I guess connecting it to the observatory computer in the same room would be one once I know the best software to use to link them.

Greg.

Hi Greg,
I use team viewer, I think it is excellent. I also allows seamless connections whilst I am away from the house.

Do you install it on both computers or just one? I went to their website and they don't say much about how it works really. Open up the software on both computers and then I can gain control of the observatory computer?

You will need to install on both machines and setup an account with them. It is free for non-commercial use.

Additionally they offer an app for mobile devices.

OK thanks for that.

Teamviewer seems to need to have both computers connected to the net.
My observatory computer is not connected to the internet.

Basically I want to control the observatory computer from the office computer indoors using an Ethernet cable and not via the internet.

This must be some other software unless I am not understanding teamviewer properly.


Windows has remote desktop I think.

Hi Greg,

Most modem routers have multiple Ethernet ports on the back so you
can create your own intranet.

If the cable won't reach your modem and if you are using a wired
network already, then consider purchasing a small network switch
and locate it next to your office computer.

The topology would then be that the network switch would have three
cables going into it. One from your modem, a short one to your office
PC and the third to the observatory.

If the observatory PC has a version of Windows that supports it,
consider using Microsoft Remote Desktop. A Remote Desktop server
is generally not supplied with the Home versions of operating
systems such as Windows 7 but is standard in the Professional editions.

Alternatively, consider using a free version of VNC, such as TightVNC.

If your office computer links to the modem via WiFi rather than by a Ethernet cable,
you might have to consider setting up the wired Ethernet port on the office
PC as a subnet. In other words, your PC might have multiple network adapters,
namely a WiFi port and a wired Ethernet port. You then need to configure
your PC so that traffic is routed over the correct port.

Just bear in mind that TeamViewer had a bit of a security breach.

On the same network TightVNC is a fine choice. (Or on the wide network, just harder to setup)

Thanks Gary.

I repaired my long cable (it must be 75 metres long!) and I got remote desktop working. I just had to enable the observatory computer (Wins 7 ultimate) to accept being run in remote desktop.

It all seems to run now. So now I have to run the cable under the house and into the observatory and do a test run and make sure everything still runs and the data is saved.

Then next step will be to install and run SGPro and get it to do meridian flips so I don't have to stay up to do that or do some compromise and lose the full valuable imaging time of clear nights.

Then get an Lodestar X2 and install an Optec Lacerta continuous autofocus on my MMOAG guider using Focuslock. Maybe even an AO on the Honders later on - even more adapters!

Greg.

Team Viewer works for me over about 40 meters and two switches. Really handy when it's cold.

Yes it would be handy then. But Teamviewer seems to require an internet connection to work?

I've had success using TeamViewer with a connection over LAN as per these instructions.

Thanks Jerome. If I have troubles with Remote Desktop I'll try that out.

Radmin. Always works, no internet connection required. Costs $US49. Been using it for years without any issues.

https://www.radmin.com/download/

About Radmin
----------------------------------------------------------------------

Radmin is fast and secure remote control and remote access software that enables you to work on a remote computer as if you were sitting in front of it and access it from multiple places.

Radmin consists of two modules:

* Radmin Viewer needs to be installed on the local computer (for example your home PC or notebook) which you want to use to access your remote computer.

* Radmin Server needs to be installed on the remote computer (for example your office PC) that you want to access from your own one (for example your home PC or notebook).

To get started make sure Radmin Server is running on the remote computer. Then run Radmin Viewer on the local computer and connect to the remote computer.

RDP is built into all Windows. Enabled by a checkbox in Pro, but it still exists in Home - search for RDPwrap. RDP is pretty efficient, and is commonly used in data centre environments.

I'm probably the farthest from being a Windows fanboy, but it works well and is built-in.

I am with Marcus, I use Radmin mostly with team viewer for mobile devices. Be very careful with Team Viewer at present. There are some hacks going on, so you need to operate at the highest security.

a related question...

I'd like to monitor (not necessarily control) the laptop running in the observatory from a mobile device inside the house. For me it's just about being able to check it's all still ticking away.

I don't have internet up there and would prefer not to have to roll out an ethernet cable each time.

Is there something that might achieve that?

many thanks

niko

There are free RDP clients on the Google Play store that run on Android.
If there is WiFi range put a WiFi card in the PC.
Run MS Remote Desktop on the PC and connect via yor intranet.

Thanks Marcus. I remember now you telling me that before. Good to know there is a good alternative to Team Viewer. Team Viewer did not make a good first impression. The website does not really even tell you what the product is.

Thanks. That is what I got up and running yesterday and it seems to do what Marcus mentions about Radmin. The proof will be in its use which will be in a day or two.

Thanks Paul. Yes I found having to basically hand over control of your computer to a site on the net a bit disconcerting. Hacks was the immediate thought I had.


I'll see how Remote Desktop works out and post the results here. The price is good - free.

Greg.
